Patent number: 9706068Abstract: An upstream-side unit of a reading unit of an automatic document feeder has protruding portions that protrude toward a surface that forms a document feeding path in a mechanism body unit on both sides of a document in the width direction outside a feeding portion that forms the document feeding path. Positioning of the upstream-side unit provided so as to be rotatable with respect to the mechanism body unit is performed by making protruding portions come in contact with a guide surface of the mechanism body unit, the guide surface forming the document feeding path. By adopting this configuration, because the protruding portions provided on both sides of the document in the width direction outside the document feeding path are used to perform positioning, it is possible to increase the accuracy of clearance for allowing a document to pass through the document feeding path.Type: GrantFiled: February 23, 2016Date of Patent: July 11, 2017Assignee: Seiko Epson CorporationInventors: Seiji Kawabata, Soichiro Kii

Patent number: 8528894Abstract: A transport device includes a set section, a sheet sensor, and a feeding member. When a detection member does not retract, the sheet sensor outputs an OFF-detection signal. The feeding member is displaced between a feed position and a non-feed position on the basis of the detection signal. At the feed position, the feeding member comes in contact with the sheet set in the set section from above and feeds the sheet toward the downstream side on a transport path. At the non-feed position, the feeding member is separated upward from the feed position. A method, which detects a sheet in the transport device, includes displacing the feeding member from the non-feed position to the feed position, and detecting that the sheet does not exist in the set section when an OFF-detection signal is output from the sheet sensor while the feeding member is positioned at the feed position.Type: GrantFiled: July 31, 2009Date of Patent: September 10, 2013Assignee: Seiko Epson CorporationInventors: Toshikazu Kotaka, Yosaku Tamura, Seiji Kawabata, Kensuke Tamai, Hidetoshi Kodama, Soichiro Kii

Patent number: 8292289Abstract: A transport device, which transports a sheet set in a set section toward the downstream side on a transport path, includes a restricting member. The restricting member is provided at a set position of the sheet in the set section, and is displaced to restrict the sheet moving toward the downstream side on the transport path. The restricting member includes a restricting section that comes in contact with a front end of the sheet from the downstream side on the transport path, and is rotatable about a shaft extending along the transport path so as to be displaced between a first position where the restricting section protrudes on the transport path and a second position where the restricting section retracts from the transport path.Type: GrantFiled: July 31, 2009Date of Patent: October 23, 2012Assignee: Seiko Epson CorporationInventors: Toshikazu Kotaka, Yosaku Tamura, Seiji Kawabata, Kensuke Tamai, Hidetoshi Kodama, Soichiro Kii
